2019-1-1  The milling process is difficult to control due to large input disturbances. The main input disturbances are variations in the size distribution and hardness of the ROM ore fed to the mill (Coetzee et al., 2010). Commercial camera systems are available to measure the size distribution of the feed ore to a mill.
